Sentiment Analysis API V1.0 (BETA) | Java Snippet
In 'Your Active Web Service list' click on the application name to
have access to subscription details, including the PublicAccessID
and the SecretAuthKey
Replace the PublicAccessID and SecretAuthKey in the code snippet below with yours data.
The PublicAccessID key is sent as clear text, and is used to identify both user and application. Our platform uses an hash based verification system to check the data integrity and the user identity.
The SecretAuthKey is only used locally to generate the hash, and it's never transmitted over the network. You never have to send it. Keep it secret!
